IPN TRIANGULATION OF GRB010119 (SHORT/HARD)

Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>
K. Hurley, on behalf of the Ulysses GRB team,
T. Cline, on behalf of the Konus-Wind and NEAR GRB teams,
and E. Mazets, and S. Golenetskii, on behalf of the KONUS-WIND GRB team, report:

Ulysses, NEAR, and KONUS-WIND observed this GRB at 37179 seconds.
As observed by Ulysses, it had a duration of approximately   0.2
seconds, a 25-100 keV fluence of approximately  3.2E-07 erg/cm2,
and a peak flux of approximately  1.3E-06 erg/cm2 s over 0.25 seconds.
Its duration and spectrum place it in the "short/hard" burst category.
We have triangulated it to a preliminary, 3 sigma error
whose approximate area is  11. sq. arcmin. and whose
coordinates are:

    RA(2000)                              DEC(2000)
 ERROR BOX CENTER:  18 h 53 m 49.50 s     12 o  1 '  12.50 " 
 ERROR BOX CORNER 1: 18 h 53 m 34.45 s     12 o  1 '  41.48 " 
 ERROR BOX CORNER 2: 18 h 53 m 50.67 s     12 o  2 '  39.70 " 
 ERROR BOX CORNER 3: 18 h 53 m 48.33 s     11 o 59 '  45.30 " 
 ERROR BOX CORNER 4: 18 h 54 m  4.57 s     12 o  0 '  43.49 "

From
Edo Berger at Caltech <ejb@astro.caltech.edu>
E. Berger (Caltech) and D. A. Frail (NRAO) report on behalf of a larger
collaboration:

"Beginning on January 20.50 UT we observed the IPN error box of the
short/hard burst, GRB010119 (GCN#916) with the VLA at 4.86 GHz.  We find
no new sources which are not cataloged in the NRAO VLA Sky Survey (NVSS),
with a flux density larger than 350 microJy (5-6 sigma)."

From
Paul Price at RSAA, ANU at CIT <pap@srl.caltech.edu>
P. A. Price, G. Morrison and J. S. Bloom (Caltech) report on behalf of the
larger Caltech-NRAO-CARA GRB collaboration:

"We observed the IPN error box of the short/hard GRB010119 (Hurley et al.,
GCN #916) with the Palomar 60-inch telescope on 2001 Jan 20.56 and 21.57 UT
(1.13 and 2.14 days after the burst respectively) in difficult
conditions.  In particular, the seeing was ~ 5.5 arcsec and 3.5 arcsec for
the two epochs, respectively.  From visual inspection of the combined images,
we do not detect any objects within the error box that are not present on the
Digital Sky Survey 2 red plate.  Limiting magnitudes of our images are
R ~ 18 mag and R ~ 21 mag for the first and second epoch respectively,
based on comparison with stars in the USNO-A2.0 catalogue.  The quality of
the first epoch image does not allow us to search for variable objects
between the two epochs."

A. Oksanen and M. Moilanen (Nyrölä Observatory GRB-team),
H. Yamaoka (Kyushu Univ. VSNET GRB-team), and
A. Henden (USRA/USNO) report:

We have observed the entire IPN error box of GRB010119 
(Hurley et al., GCN 916) as part
of the monitoring effort by the AAVSO GRB network.
This GRB was of the short-hard variety and so is of
considerable interest.  However, at a galactic latitude
and longitude of bII=4.9, lII=43.9, the burst occurred
in a dense starfield with no visible background galaxies,
indicating considerable extinction.
  The observation was made with the Nyrölä Observatory
0.4-m telescope and Rc-filter on 010121.17 UT, between
the two Palomar observations reported by Price, et al.
(GCN 919).  A total of 12 two-minute exposures were stacked,
yielding a limiting magnitude of approximately R=19.5 in
3.4arcsec seeing.  The resultant image can be found at
http://www.jklsirius.fi/grb/grb010119nyt.fit
All objects on this image are also visible in the
scans of the POSS-2 red plate from the NOFS PMM pixel server.
